Last post by zook2 - June 25, 2025, 06:31:44 AMIf you look up Bealock (6679,2444) on the BB server, most of it is far to the northeast, near Bimblemere. It's cosmetic, but looks a bit buggy.

Simutrans-Extended development / Re: Tweaking industry growth t...
Last post by martin509 - June 24, 2025, 09:19:26 PMAlright, it has been a bit (I ended up taking a break from this due to real life), but I am back to working on this project!
Some updates: First, I have gotten started on the translation process for the 'number of translators' setting name, though have not logged on to Simutranslator yet to add a note there. More notably, I have what I think is a good working savegame conversion scheme working!
I ended up not doing either of the ideas I had previously come up with for translating old savegames. The first idea, a simple 'fudge factor' (i.e. dividing the industry density proportion by some number to get what it 'should' be for this new system) did not sit right with me, and seemed to vary greatly between worlds. The second idea, recalculating the industry density proportion by assuming the current density of consumers in a world was fine, also did not sit right, as part of the entire impetus for this project was to fix underpopulated consumers in worlds.
I ended up with a somewhat complex algorithm that tries to estimate what the industry density target should be, by taking into account current overproduction. Here are the steps:
- First, we get what the 'consumer-only' industry density currently is on the map.
- Next, we get the total production and consumption for all 'final' goods (goods that are consumed by at least one consumer industry). We multiply this by our consumer density to get our 'target density'. For instance, if I currently have a consumer density of 40 for a bunch of pubs, and I have a brewery that overproduces beer for them by a factor of 6, then our target density is going to be 240 (at first).
- From there, we also get the difference between the target density and the current consumer density. For our pub example, this would be 200.
- We subtract this difference from our 'old density' (that is, the industry density counted via the old method where we count producers and manufacturers). Let's say that old density is 800, so that subtracted difference is 600.
- We then multiply our target density by the fraction of (old density - difference)/(old density). This step is to essentially compensate for the extra industry density adding our consumers would add under the old model. For our current example, this means our target density of 240 gets multiplied by 640 and divided by 800, for a new target density of 180.
- We then use this target density for the industry density proportion calculation - for reference, multiplying target density by 1,000,000 and dividing by total world population.
A bit complex? Perhaps, but I think the results speak for themselves. In an experiment with a circa-1910 Pak128Ex savegame (using the current version and not my modified version I was working on), there was a burst of construction that eventually trailed off within around 3 years of loading the old save, filling in a number of consumer industries for the major bottlenecks (in this particular world, it was beer and steel that was overproduced). By the time it trailed off, things had gone from <10% utilization to >75% without any entirely new supply chains being added, which is roughly what I wanted.
Anyways, all this to say - this project is not dead, and work continues! The savegame compatibility code should be on GitHub now for you to peruse.

The buildings are beautiful, I think the one with Maradona should be made an attraction of the city, so that it generates a particular traffic of tourists and mail.
